摘要： 针对科技信息资源分散于基层科技机构的现状，提出一种基于SaaS模式的在线科技信息资源托管系统。采用完全隔离的多租户数据体系结构及分布式数据库代理策略，将系统架构分为应用层、数据库调度层和数据库层，设计包括多租户数据结构与分布式数据代理的系统核心机制。实验结果表明，该系统可以对多租户接入的科技信息资源进行在线管理，实现信息资源的汇聚与托管。

Abstract: In view of the present situation that science and technology information resources scatter in grass-roots institutions, this paper proposes an online escrow system based SaaS mode for resources of science and technology information. It uses complete isolation of multi-tenancy data structure and more distributed database agent strategy to divide the system architecture into the application layer database scheduling layer and database layer. It designs the core mechanism including more multi-tenancy data structure and distributed data agent system. Experimental results show that the system can manage technology information resource from multi-tenancy online and achieve information resource gathering and trusteeship.
